,Letters Patent No. 100,807, llated March 15, 1870.

VAPOR-BURNER FOR COOKING OR HEATING.

The Schedule referred to in these Letters Patent and making part of thesame First, my invention consists in a novel method of combining aforaminousdiaphragm, on the surface of which the vapor is burne d,'.witha mixing-chamber,

the walls of which are partly foraminous, so as to al low the requisitequantity of atmospheric air to enter the mixing-chamber, while at thesame time it prevents an ignition of the vapor inside the chamber.

This chamber restsv on a perforated disk, of copper or brass, which,constituting the generator, has attached to it a series of, copper orbrass rods,bending over the upperdiaphragm,and forming effectiveheat-conductors to the generator.

Secondly, my invention further consists in a novel method .of combinganArgand burner with amixingchamber, foraminous diaphragm,heat-conductors, and generator, which insures a much more perfectcomhnstiou of the vapor. I

In the accompanying drawings which make part of this specification-Figure 1 is a vertical section through my improved burner.

Figure 2 is a similar view of the Argand burner.

Figure 3 is a view of the perforated generatingdisk, looking down uponit.

Figure 4 is a similar view of the Argand burner, showing part of theupper diaphragm and part of the distributing-chamber.

.Petroleum or other analogous fluid is fed from a reservoir, A, through.a pipe, B, to agenerator, 0 f, where it is volatilized and whence itescapes in the form of vapor, into the mixing-chamber ,1), consisting,

by preference, of an inverted frustnn-i of a cone, provided with theforaminous diaphragm .E, and resting on the peiforateddiskf. i

As the vapor escapes through the valve 0 into the chamber 1), air entersthrough the apertures of the disk f, and the foraminous part G H of thechamber D,becoming thoroughly milked with the vapor.

The vapor, being ignited above the diaphragm E,

burns with an intense, clear, and steady heat, which, striking theconductors t M a, communicates ample heat to the generator U f to keepup the volatilization of the fluid as it enters from the reservoir A.

In fig. 2 I have sl own how the principle of the Ar-' gand burner may beadapted to my generator. The vapor in this case passes first into adistributing-chambe'r, K, from whence it passes either through anannular slot, or in minute jets into the mixing-chamber D, thus causinga more intimate mixturewith the atmospheric air entering through thedisk f and the foraminous part G H of the mixing-chamber D.

Oonneetedlwith the distribut-ing-chamher K is a tube, L- M, admittingair. at L and carrying it at M into the center of the flame, still morepromotes the perfect combustion of the vapor. The construction of thegenerator 6 f and the conductors i i t a is the same as in fig. 1.

A conical ring, N N, may be placed above the diaphragm E to concentratethe flame in either form of j a burner.

Now, while I do not broadly claim the use of a ibraminous diaphragm, norof conductors of heat, nor

of a mixing-chamber, v

What I claim .asmy invention, and desire to secure by Letters'Patent,isj 1. The perforateddisk of the generator 0 f, substantially as setforth.

2. The combination of a foraminou's diaphragm, on the surface of whichthe combustion is eifected, with a mixing-chamber of either solid orpartly foraminous walls, surrounded by a series of conductors, and agenerator with perforated disk to which these.condoctors are attached,substantially as set forth.

3. The combination of a foraminous diaphragm with a mixing'whambcr,having an air-tube in the center, and a generator with adistributing-chamber, through which the vapor passes, either in minutejets or through an annular opening into the mixing-chamber,substantially as set forth.-

In testimony whereof I havehcrennto set my name.
